To ALLWHOM 1T MAY CONCERN.

Be it known that I, WILBBR F. ARNOLD, of New Britain, county 'of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Lock Snap-Hook; and to enable others skilled in' the art to maire and use the same, I will proceed to ydescribe by referring to the drawings, in which the same letters indicate like parts in each o f the figures. i

' The nature of this invention willbe understoodjrom the specifications and drawings.

The objectfdesired to be attained thereby is to lock-the latch when it is hooked into a `loop or ring,'and thereby prevent it from becoming detached from said loop or ring, by anything striking against the latch. Inthe accompanying draivings i I Figure 1 is a side view of the hook.

' Figure 2 is'a front side vievv.

Figure 3 is a. back. side vien'. v

Eigure 4 is a. sectional side view.

va is the strap-loop.

b is a hook, by which it is secured' to any desired yplace or article.'

cris therlatch, which closes up the opening throughwhich a loop or ring passes into the hook.

w d is a thumb-latch, which serves both to lock the Vlatch c, and to press open the latch after it (the inner end of the thumb-latch d) is relieved from a. notch, e, in the -inside of the latch.

f is a spring-supporter, and held in its proper position by a bar,'h, cast or Iliade iii the back edge of the opening z', formed in the body of the hook, one'end of which bears against the thumb-latch, and thepther in a depression, 1c, at thelower end of th opening.

Thus it willgbe seen that a cheap, simple, and eilicient hook is produced, which can be easily detached from its mooring by pressing the thumb-latch,whch unlocks the latch proper, and at the same time`presses open said latch. l I believe-I have thus shown the nature, construction, and advantage of thisinvention, so asto enable others skillediu the art t o make and 'use the same. What I claim, therefore, 'and desire to secure -by Letters Patent, is-

The loek thumb-latch d, with' the latch c and hook b, substantially as and for the purpose described.
